Our models typically wear US Size 2-4 or Australian Size 6-8, X-Small, Small, or One-Size garments.
On each product page, we provide the model's measurements and what size she is wearing to help guide you.
You can refer to the charts when selecting sizes but please note that sizes cannot be guaranteed and might vary slightly between brands.
If you need any advice about sizing, please feel free to drop us a line at: service@sunnoss.com
The measurements in the description of individual products are taken only across the front side of the garment, not around the circumference (e.g. chest and waist).
If you can't find a completely satisfactory size in our size chart, don't worry! Feel free to contact us anytime at service@irispetal.com or through our online customer service. Our team is more than happy to provide personalized advice, recommend alternative styles, or assist with customization needs. Your comfort is our top priority!

The shoe you reach for when the training says speed. Strides. Steep climbs. Intervals with intent.
Kjerag 02 is built for those sessions in the mountain that sharpen your edge. When your feet turn over quicker, your breath syncs with the trail, and you hear a voice whispering, “you have more to give.”
This isn’t just a race-day shoe. It’s for the workouts that build you. For the days that effort meets output. Where faster becomes a mindset and not just a number.
The Kjerag 02 carries the same DNA as the original, now re-engineered for more speed, comfort and durability. We kept the tried-and-tested outsole, then refined everything else to deliver lasting performance and comfort, mile after mile.
It’s no longer just Kilian’s shoe. It’s yours. For whatever your fast looks like. Whether that means time, terrain, or simply a snappier feeling in your stride.
In a deep burgundy tone ideal for trail running in any condition, the Kjerag 02 combines style with performance. Designed for fast trail running, it delivers more responsiveness, more comfort, and more performance than ever before.

Matryx® Jacquard SIngle Layer | VIBRAM® Megagrip | VIBRAM® Litebase | EExpure + midsole | TPE based - 35% higher rebound & resilience
A new generation of foam engineered specifically for trail-running shoes, used on 6mm overall drop. The EExpure foam midsole sits in direct contact with your feet, for best-possible propulsion and compression, less slippage, and way fewer blisters!

Snowy boulders, wet roots, muddy paths – whatever you're tackling, Vibram® MEGAGRIP is both super-sticky and extra-durable. With ground adaptation that makes your feet, muscles and joints one with nature.
The Vibram® Litebase outsole drastically reduces 30% of the overall sole weight, through a reduction of the sole thickness by 50%. While retaining the perfect shape, 3.5mm lugs. The total weight of the shoe is only 200g (size 8 UK).

The exceptionally breathable and durable upper is weaved from individually coated polyamide and Kevlar® yarns. Produced in Ardèche, France, the dyeing process uses between 50-95% less water than other methods.
